the brake system, but this is not a
malfunction.
■Automatic reactivation of TRAC
and VSC systems
After turning the TRAC and VSC
systems off, the systems will be
automatically re-enabled in the fol-
lowing situations:
●When the engine switch is turned
off
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the engine
off. The EPS syst em should return
to normal within 10 minutes.
